摘要：

Thermoluminescence (TL) of tellurite-phosphate glass of the composition of (TeO20.81-P2O50.19) doped with different concentrations of Nd2O3 was prepared. The optimum concentration of Nd2O3 was experimentally determined as 10(-3) wt% Nd2O3 in this glass. TL showed a single, isolated glow curve which peaked at approximately 498-513 K (depending on the Nd concentration). This peak is very suitable for radiation dosimetry, and obeys second-order kinetics. The TL response against the irradiation dose was found to be linear in the low-dose region (11.2-224.2 muGy), indicating the high sensitivity of our glass samples to low-dose gamma rays. Finally, the trap depth was also calculated, using methods concerning the second-order kinetics.
